The Brain as a Guessing Machine and its Basis on Past Experience

"The brain is like a guessing machine," says the speaker. It's constantly making guesses based on past experience to determine how to react to different stimuli.

This decision-making process is not an intellectual guess, but rather a motor plan that changes the body's internal state to support physical movements. The brain uses past experiences to create these plans by reinstating bits and pieces of similar signals.
